UNSPSC 81151804: Hydrological surveys

UNSPSC 81151804 Hydrological surveys, a Commodity code, encompasses groundwater investigations, aquifer assessments, well design and monitoring, hydrogeological modeling, and water resource impact analysis that state and local water authorities and public institutions procure to support infrastructure planning, regulatory compliance, and water-supply operations. Universities, regional water authorities, and local fire districts are the primary issuing bodies currently soliciting under the code, with work spanning geological characterization beneath existing campuses and buildings, multi-year as-needed hydrogeological task-order contracts, and integrated professional services agreements that bundle hydrological work with architectural, surveying, and environmental consulting. The scope reflects a shift toward comprehensive subsurface data integration, GIS-based geodatabases, permitting support, groundwater and surface water modeling, well testing and abandonment, aquifer impact assessment, and water-quality monitoring programs rather than discrete survey projects.

The University of Texas at Austin, Tampa Bay Water (serving Hillsborough, Pasco, and Pinellas counties in Florida), and the Pinellas Suncoast Fire & Rescue District represent recent activity in Texas and Florida. The University of Texas at Austin issued RFP 26PSS002 on June 23, 2026, for a Campus Geological and Hydrogeological Study with qualifications due July 17, 2026, seeking to characterize subsurface geology and consolidate existing hydrogeological data into a web-based GIS platform while addressing historical groundwater intrusion in building infrastructure. Tampa Bay Water released RFP 2027001015 on May 8, 2026, selecting five qualified firms for five-year as-needed hydrogeological services with proposals due June 30, 2026, covering permitting assistance, modeling, well inspection and rehabilitation, and aquifer impact analysis. The Pinellas Suncoast Fire & Rescue District included Hydrologic Services as one of six professional service categories in its continuing-services RFQ 26001 posted April 13, 2026, for design and inspection work across six service lines, with qualifications submissions required by December 1, 2025. All three Florida opportunities explicitly evaluate or incentivize Minority Business Enterprise certification as a scoring criterion.
